Struct kernel::sync::lock::Guard

source · 
pub struct Guard<'a, T: ?Sized, B: Backend> { /* private fields */ }
Expand description

A lock guard.

Allows mutual exclusion primitives that implement the Backend trait to automatically unlock when a guard goes out of scope. It also provides a safe and convenient way to access the data protected by the lock.
